Opportunities and Challenges in China-US Lunar Research Cooperation

Liu Dunyi, a senior researcher at The Beijing SHRIMP Center and an expert in isotope geochemistry, recently discussed the potential for accelerated progress in lunar science through collaboration between China and the US. In a conversation with the Global Times, he emphasized the advantages each country possesses in this field and lamented how the Wolf Amendment creates barriers that prevent fruitful scientific partnerships.

Throughout his distinguished career, Liu has conducted research on various lunar samples, beginning in 2007 with those from the Apollo missions. He recalls the strict regulations that accompanied the samples, which limited direct collaboration with American scientists. Liu also praised the rapid analysis of lunar soil from China's Chang'e-5 mission, which yielded significant findings about magmatic activity on the moon, extending its geological timeline.

His latest efforts focus on samples returned from the Chang'e-6 mission, which have revealed new insights into the moon's geological history, including evidence of magmatic activity on its far side and paleomagnetic field data. Liu expresses a sense of national pride in conducting independent research and looks forward to comparing near-side and far-side lunar sample structures.

Despite legal restrictions preventing US institutions from collaborating with Chinese scientists on lunar research, Liu noted that he has been able to work with Australian scholars, showcasing the willingness of the wider academic community to partner with China. He believes that a cooperative approach could bring substantial benefits, stating that the combined expertise of American and Chinese scientists could significantly enhance lunar research efforts and overall scientific advancements. However, the Wolf Amendment remains a notable obstacle to achieving this collaboration.
